Brichka S. The development of the fundamentals science of functional materials with nanotubes

The dissertation is devoted to the study of theoretical and experimental regularities of the processes of formation of functional materials on the basis of carbon and halloysite nanotubes, the establishment of their structural and functional properties. A theoretical model for the synthesis of carbon nanomaterials using templates is developed, which includes the formation of carbon vapors, their movement to the pores and deposits in the solid pores, the formation of carbon-carbon bonds and successively nanotubes graphene layers. The technological parameters of the synthesis of carbon nanotubes - temperature, time, speed of the precursor flow - are established. The temperature of obtaining nanotubes from the typical 600-700 to 400 °C has been lowered, which reduces the energy consumption of their production. A method for the synthesis of carbon nanomaterials using a water soluble catalyst carrier has been developed. A series of adsorption materials with a specific surface area in the range of 200-800 m2/g with capacity up to 0.5 mmol•g-1 relative to benzene, phenol, benzoic and cholic acids was obtained. It is shown that changing the technological conditions of synthesis of adsorbents and, accordingly, the surface content of oxygen, it is possible to improve the efficiency of adsorbents to certain molecules. Low-toxic functional materials based on nanotubes with oxides as anti-corrosive additives with high (more than 80-90%) degree of aluminum alloy protection are offered. The elasticity of carbon nanotubes of different diameters is established and the creation of nanotubes with a diameter of less than 2 nm is predicted to be based on textile material with extreme mechanical characteristics. The treated nanoparticles of silver textile materials exhibit bactericidal properties. The technology of processing of textile materials by nanotubes is proposed for creation of products based on them with improved operational properties. Sun glasses with halloysite nanotubes with hypoallergenic and anti-inflammatory properties have been developed and introduced into production. According to photoprotective activity in the range 290-320 nm, they exceed the action of analogues. Agar-agar and chitosan hydrogels with nanotubes for medical dressings that protect the skin in the UV range are created.
